Question 36

The OLA device is used in an optical amplification station; it amplifies the optical signals transmitted in two directions respectively. Which boards are required for OLA sites? (Multiple choice)

A.OAU1

B.ST2

C.SFIU

D.SCC

Question 37

In the SDH multiplexing structure, the rate represented by VC-12 is () Mbit/s

Question 38

When super 100G/100G and 10G are mixed adjacently, the optical power of super 100G/100G signal should be higher than that of 10G signal, but it should not be higher than the single-wave nominal value of the optical amplifier board.

A.True

B.False

Question 39

Which of the following statements about overhead bytes is wrong?

A.B1 is Bit Interleaved Parity-8 (BIP-8). This byte is used to monitor the regenerator part layer for bit errors

B.E1 and E2 are wired bytes. These bytes are used to provide voice channels for order line connections.

C.JO is the regenerator section trace byte. This byte is used to repeatedly send the segment access point identifier so that the receiving end can verify its continuous connection with the designated sending end

D.A1 and A2 are framing bytes. These bytes are used to separate STM-1 frames in the signal stream

Question 40

A.SNC /N

B.SNC/S

C.SNC/I

D.SNC/S and SNC/N
